provements in or Relating to Metallic Packing for Stuffing-Boxes and theLike, of which the following is a specification.

- This invention relates to improvements in. metallic packings forstuffing-boxes and the like, and more particularly for the stuflingboxesof gascompressors, especially those used for compressing ammonia orgases of the like tenuity, and I will, by way of example, describe myinvention as applied to such stuffing-boxes.

I have illustrated my invention in the accompanying drawings, in whichFigure I is a longitudinal section on the line A A of Fig. II, and Fig.II an end view of a stuffing-box constructed according to my invention.1

In the bottom of the stufling-box l I fit a ring 2, which I will termthe bottom ring. This ring is held in place by a sleeve 3, which is asliding fit in the stufling-box 1 and which is of such length as to bemaintained in position by the cover 4, which closes the stuffingbox.Between this cover 4 and the flange 5 of the stuffing-box I interpose awasher 6, of rubber or the like material, and between the bottom ring 2and the bottom of the stuffingbox I interpose another washer, 7, of thesame material, which two washers, in conjunction with the bottom ring 2,the sleeve 3, and cover 4, serve to form a gas tight chamber into whichand out of which no gas can escape except that which passesthe'packingrrings 8 and 8 of the metallic packing.

Inside the sleeve 3 the metallic packing proper is located, and itconsists of two series of antifriction-rings 8 8, of the usual conetype, carried in two containing sleeves 9 and pressed apart by acompressed interposed spring 10, the pressure of which is transmit tedthrough suitable bearing-rings 11. The

lower containing sleeve bears against the bottom ring 2 and the upperone bears against an end ring 12, which preferably has a sphericalseating 13.

The sleeves 9, the spring 10,

the bearing-rings 11, and the two end rings 12 are smaller in diameterthan the interior of the gas-tight sleeve 3, and are therefore free tofollow any small lateral movement of the rod14.

111 the event of any gas passing the inside of the packing-rings 8 intothe gas-tight sleeve I provide means for dealing with it as follows:

I form an annular groove 15 in the inside wall of the stuffing-box anddrill one or more holes 16 in the gas-tight sleeve 3, through which theinterior of the sleeve communicates with the groove 15, which in turncommunicates by a suitable pipe 17 with a receiver or other suitablevessel to which it is desired to lead the gas. The pipe 17 is providedwith a flange attachment 18, so that it may be easily dis= connected. Ialso provide against escape of gas past the outside packing-rings 8 tothe atmosphere by forming in the cover 4 an oilchamber 19, in which oilis retained by packing-rings 20, held apart by distance-pieces 21, thewhole being held in position by means of a screwed cap 22 and gland 23.Oil is fed into this chamber 19 either by pressure or by grav ity, theoil passing through holes 24 in the distance-pieces 21 into contact withthe rod 14, thus forming a liquid seal to prevent leak= age of gas. Theoil is fed into the chamber 19 through the passage 19, leaving the sameby the upper passage 19.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1 In a stuffing-box, in combination: the rod; the metallic packingfitting the rod; and the gas-tight chamber formed in the stuffing= boxand in which the packing is inclosed and which is provided with anoutlet through which any gas.which may accumulate may be withdrawn;substantially as described.

2. In a stuffing-box, in combination; the rod; the metallic packingfitting the rod; and the gas-tight chamber formed by a sleeve, an

end washer and ring and a gland, provided 3. In a stufling-box, incombination; the rod; the metallic packing; the ring; the

washer; the sleeve; and the gland provided with a liquid seal consistingof the liquidchamber and packing-rings and means for holding the latterin position, substantially as described.

4. In a stufiing-box, in combination; the rod, the metallic packing, thesleeve, the ring, the washer, and the gland provided with anoil-chamber, packing-rings, distance -piece and means for holding thepacking-rings in position in the oil-chamber; substantially as describedand illustrated.

5. In a stuffing-box, in combination; the rod, the metallic packing, andthe gas-tight chamber having a liquid seal formed by a liquid-chambercontaining packing-rings and having an inlet and an outlet for theliquid; substantially as described and illustrated.

6. In combination in a stuffing-box, a metallic packing comprising twosets of packing-rings, containing sleeves in which the two sets ofpacking-rings are located, a spring interposed between the two sets ofrings, the pressure of said spring being communicated to the containingsleeves, and a sphericallyseated ring between one of the sleeves and theadjacent wall of the box, substantially as described.

7. In combination in a stuffing-box, the metallic packing, a gas-tightchamber within the box inclosing said metallic packing and hav ing anoutlet to lead the gas away as it accumulates and a chamber for a liquidseal which chamber is provided with an inlet and an outlet,substantially as described.

8. In combination with a stuffingbox a sleeve th erein fitting with itsperiphery closely against the inner periphery of the box, aring 2 with awasher 7 between the inner end of the sleeve and the bottom of the box,a cover 4 for the box pressing against the end of the sleeve, a washer 6between the cover and the box and packing means within the gas-tightchamber formed by the sleeve-ring, washers and cover, said packingsurrounding the rod, substantially as described.

9. In combination a stuffing-box, a metallic packing within the box, acover for the box and a sleeve surrounding the packing making agas-tight joint at one end with the bottom of the box and at the otherend with the cover, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses;

HENRY JACKSON GOLD.
